7 Claims.

This invention relates to windows and in more particular to the closureassemblies for the ventilating areas in windows.

This is a continuation-in-part of my copending application Serial No.129,669 flledMarch 8, 1937,

for'Window.

4 An object of this invention is to provide a closure provided with aflexible Contact engaging the frame surrounding the closure.

Another object of this invention is to provide a closure for Ventilatingareas of windows that is cheap, eicient, durable and dependable, thatmakesy good contact so as to protect the interior of the building fromthe elements.

unitary structure( for the closure and its screen that may be insertedas a unit into the Ventilating area.

Another object of this invention is to provide a composite frame for aWindow wherein parts are molded from plastic molding material.

Other objects and advantages reside in the construction of parts, thecombination thereof and the mode of operation, as will become moreapparent from the following description.

In the drawing,

Fig. 1 shows a vertical sectional View of the preferred embodiment.

` Fig. 2 is a sectional view taken substantially on the line 2-2 ofFig. 1. y

Fig. 3 is a vertical sectional View of a modification.

Referring to the drawing, a plurality of transversely disposed T-shapedduo-functional muntin and detention bars divide the window into aplurality of spaces, some of which are provided Awith window panes 22,leaving a group of spaces 24'Vacant as a Ventilating area. In order toprotect occupants of the building during inclement Weather it isdesirable to provide a suitable closure for the Ventilating area 24. Theclosure includes a sheet metal member 26 pivotally attached by hinges 28to the muntin bar extending across the top of the Ventilating area. Thetop and bottom portions of the sheet metal member 26 are provided with'channels 30 preferably integral with the body portion 26. The channels30 house sealing material 32, such as felt or the like. The felt isadapted to abut the inwardly projecting flanges of the muntin barsbounding the top and the bottom of the Ventilating area.

'I'he sides of the closure 26 are preferably provided with reentrantiianges 34 adapted to grip a metallic weather stripping member 36substantially U-shaped in cross sectional area. One leg of each of theweather stripping members 36 is mounted in the bight formed between themain body portion 26 and the reentrant flange 34, and clamped therein.The other leg oi each of` the weather stripping members forms a flexiblecontact intermediate the closure and the inwardly projecting flanges ofthe vertically disposed muntin bars bounding the Ventilating area. Fromthe foregoing description it can be readily seen that the closure ismounted Within the confines of the muntin bars, the main body portion 26being in substantial alignment with the glazing 22.

Although the main body portion 26 has been described as consisting ofsheet metal, it may consist of 'a sheet of translucent or transparentmaterial molded from a suitable plastic molding material, such asnitrocellulose or phenolic condensation products.

The closure is adjusted and held in closed-posi- `tion by a chain 3B,which may be locked onheld taut in any suitable manner. As it is notfeasible to have the muntin bars 20 extend continuously across theVentilating area, suitable detention bars 40 are utilized to preventescape oli bodies through the closure. In order to prevent the passingof small bodies and in order to provide protection against insects, ascreen 42 iixedly attached to a metallic frame 44 is mounted over theVentilating area in contact with the flanges of the muntin bars 2libounding the Ventilating area. Y For some installations the screen frame44 and the detention bars 40 mayy be xedly attached to each other.

Referring to the modication disclosed in Fig. 3, the closure and screenassembly have been mounted so as Ato be partially enclosed by the stemsof the muntin bars 20. In this modification the movable closure 'lllincludes a frame made either from metal or from suitable moldingmaterial. Said frame includes members 12 substantially L-shaped in crosssectional area. The closure 'l0 is pivotally attached by hinges 14, onlyone of Which is shown, to the web of the muntin bar 20 extending acrossthe bottom of the ventilating area. The closureis held in closed posi-vtion `by a suitablev latch 16. v

The closure assembly 80, which has been shown as a screen, projectsthrough the Ventilating area. The screen frame 90 is formed fromanglebars made either from metal or from a plastic molding material.These angle bars have the flanges 90a, projecting through theVentilating area and supporting the screen 84 suitably attached thereto.An abutment or snubber 96 attached to the lower flange 90a holds thescreen frame at a proper height. A stop 91 is arranged in hookedrelation lill Cil

with the flange of the detention bar 20 to prevent the screen frame frombodily removal inwardly. 'Ihe upper flange 90a is held in position by adiagonally arranged screw 38.

Flexible metallic members 99 are arranged in.

hooked relatio-n over they outwardly projecting flanges 93h of y theangle bars 90 forming the frame for the screen. The ilexible members 99are clamped between the inwardly projecting iianges of the muntin bars20 bounding the ventilating area and the movable frame of the closure,so as to provide a double contact between the exterior of the window andthe closure, that is, one contact between the inwardly projectingflanges of the detention bars and the other contact with the frame ofthe movable closure.

A spring 29, which may be a coil spring, tends to bias the closure 26into open position,- so that when the chain 3B is released from theinside of thebuilding the closure 26 automatically moves into openposition.

vAlthough the preferred modification of the device has been described,it will be understood that within the purview of this invention variouschanges may be made in the form, details, proportion and arrangement ofparts, which generally stated consist in a device capable of carryingout the objects set forth, in the novel parts, combination of parts andmode of operation, as disclosed and defined in the appended claims.
